The holiday season has arrived, when revelers hit the stores or sidewalks searching for that perfect Christmas tree.

But for one couple from New Jersey, this Christmas has special meaning. Their two young sons are battling a rare disease, and a local nursery is using its sales to help.

The Leiders, of Elmwood Park, are a typical family of five, but they face an extra challenge every day -- the fight to keep 7-year-old Justin and 10-year-old Jason alive.

Both boys are in a clinical trial in North Carolina for a drug that is keeping them healthier than doctors believed they would be right now. The trial expenses are covered, but leaving their jobs one week every month has left them short on funds.

They are loyal customers of American Nursery in Fair Lawn, where they buy their Christmas tree. And this season, all trees sold there will help these boys.

Owner Gary Sandberg, a first time grandpa, has decided 10 percent of each one sold will go to the family.
